For the last 8 or so years I am running this setup sans QoS on a Dell Optiplex GX240, P4 2.8/400 FSB/256 KB cache, 2x256MB SDRAM. It boots from a 40 GB drive that is mostly empty.

My LAN makes gazilion of connections due to uTorrent and this rig pulls just fine. The soap box routers by Linksys, SMC and DLink just quietly passed out under that load (SMC was the most robust of them).

Used a Kingston 8GB USB stick for a while, but it died after 1 year, so I stick to a HDD.

Going to migrate that to an Atom 1.6 GHz box with 2GB DDR2 as soon as low profile Intel PCIe card is delivered (this Compaq has only 1 Ethernet port).

I just installed zeroshell on an APU2c4 that replaced an older Alix that worked for about 5 years and is still ok. My alix board runs zeroshell as well and maxed out the cpu on a 50 megs ISP connection when downloading torrents. Same activity on APU, the cpu is 3%.

In my setup I have a msata 16 and wle200nx . Both are supoorted well zeroshell.
However at the time of writing, cpu temp sensors and leds are not supported.

It should work. I read about "X session freezes" on bay trail platform, but I have first hand experience with the same freezes on AMD and believe this has more to do with the devs fucking up XOrg more than with Intel.
